Region based affine motion segmentation using color information

Region Based Target Detection Approach for Synthetic Aperture Radar Images and Its Parallel Implementation Nar, Fatih; Demirkesen, Can; Okman, O. Erman; ÇETİN, MÜJDAT (2012-04-26) Automatic target detection (ATD) methods for synthetic aperture radar (SAR) imagery are sensitive to image resolution, target size, clutter complexity, and speckle noise level. However, a robust ATD method needs to be less sensitive to the above factors. In this study, a constant false alarm rate (CFAR) based method is proposed which can perform target detection independent of image resolution and target size even in heterogeneous background clutter. The proposed method is computationally efficient since cl...
Region-based parametric motion segmentation using color information Altunbasak, Y; Eren, Pekin Erhan; Tekalp, AM (1998-01-01) This paper presents pixel-based and region-based parametric motion segmentation methods for robust motion segmentation with the goal of aligning motion boundaries with those of real objects in a scene. We first describe a two-step iterative procedure for parametric motion segmentation by either motion-vector or motion-compensated intensity matching. We next present a region-based extension of this method, whereby all pixels within a predefined spatial region are assigned the same motion label. These predefi...
REGION-BASED IMAGE SEGMENTATION VIA GRAPH CUTS Cigla, Cevahir; Alatan, Abdullah Aydın (2008-01-01) A graph theoretic color image segmentation algorithm is proposed, in which the popular normalized cuts image segmentation method is improved with modifications on its graph structure. The image is represented by a weighted undirected graph, whose nodes correspond to over-segmented regions, instead of pixels, that decreases the complexity of the overall algorithm. In addition, the link weights between the nodes are calculated through the intensity similarities of the neighboring regions. The irregular distri...
Region-based dense depth extraction from multi-view video Cigla, Cevahir; Zabulis, Xenophon; Alatan, Abdullah Aydın (2007-09-19) A novel multi-view region-based dense depth map estimation problem is presented, based on a modified plane-sweeping strategy. In this approach, the whole scene is assumed to be region-wise planar. These planar regions are defined by back-projections of the over-segmented homogenous color regions on the images and the plane parameters are determined by angle-sweeping at different depth levels. The position and rotation of the plane patches are estimated robustly by minimizing a segment-based cost function, w...
